- Specialist in Computer Networks
Master Computer Engineer, specialized in Computer Networks, that loves to study and understand new technologies, specially in areas of audio and video streaming, computer architectures and networks, distributed systems, embedded systems, and chip manufacturing. Understanding inner workings is my biggest motivation, as this knowledge is key to identify key indicators necessary to guarantee the performance and reliability of products and services. Previous experiences also include distributed systems of a big cloud provider and content delivery network with analysis of big data sources, technical network evangelist teaching and motivating the usage of the IPv6 Protocol, contributor of the Internet Engineering Task Force (IETF) on the development and evaluation of internet protocols.
Professional Skills
Work Experience
Since 2017
Principal Site Reliability Engineer
AKAMAI TECHNOLOGIES
Performance evaluation and improvements for live and on demand media streaming, including the impact of encoding, compression, adaptative bit rate and transport protocols (TCP, UDP, QUIC) for video transmission over internet. Analysis of content delivery network (CDN) performance based on key performance metrics to increase QoS and prevent service disruptions to customers of a globally distributed infrastructure capable of supporting more than 10 Million simultaneous users in big events like the Olympics or the FIFA World Cup. Data analyst using Python on large datasets collected from production networks with complementary usage of open source solutions, like Hadoop, Grafana, Postgres and Clickhouse. Negotiation with multiple internal teams, like software development and product management, to enable early problem detection and fixes, as well to quickly decide paths to mitigate ongoing issues. Training and mentoring of new team members
